Description

Field of the Invention The invention relates to a transport engineering, mainly to tracked vehicles with two tension wheels.

The purpose of the invention is to carry devices.

screws 17. All wheels are covered by a caterpillar 28.

The device works as follows.

When hitting the front guide of the coaxie 5 with an obstacle or hitting a cushion between him and the caterpillar 28, the force with

wheels 5 is transferred to crankshaft 6, the rod

FIG. 1 shows a diagram of a running gear 7, a two-armed lever 8, a front end 18 of the st part with a common delivery device; screw 17, the nut 19, the flange 14 and the valve; FIG. 2 — a part of the common delivery body compresses the spring 16. In this case, the sections A-A of FIG. 1. Forest 5 begins to move inward. The trailed part of the tracked vehicle contains about {in FIG. 2 to the right), interleaving the frame 1, the drive wheel 2, supporting the entire power chain, the living rollers 3, the support rollers 4, and also the screw 17 itself, the head 21 of which the guide wheel 5, slides in slot 27 pusher 26. on frame 1 by means of crank 6, stann-When eliminating overload, all the lists 7 and two shoulders 8. Rear directional elements under the action of the spring 16 the impeller 9 mounted on frame 1 are shifted in the opposite direction while crank 10, rod It, and two-head-head 2 does not resist es washer 22 at which the lever 12. Each guide yundee co-bracket 23.

Leso 5 and 9 is associated with the general handing over. When stones hit between the caterpillar

the device 13, which is made in the form of 28 and the rear guide wheel 9 or

front 14 and rear 15 support flanges, 20 by focusing it in the obstacle force from the wheel

between which the pre-9 is placed is transmitted to the crank 10, the rod 11,

spring 16 is compressed.

The flanges 14 and 15 are connected by a clamping screw 7, the front end 18 of which passes through the central hole in the flange 14 and is fixed by a nut 19. The rear end 20 of the clamping screw 7 has a T-shaped head 21 and is supported through the spherical washer 22 on the frame bracket 23

The screw 17 presses with the help of the spring JQ in the opposite direction until the flange 15 through the 16 flat washer 24, the flange 15 and the spherical washer 25 rests on the bracket 23.

Due to the inclined installation of the crank 10, the guide wheel 9 is also protected against vertical overloads when it hits the ground.
